ARM: dts: rockchip: add cru nodes and update device clocks to use it

A patch from »Clock support for rk3066,rk3188 and rk3288« in state Mainline for linux-kernel

From: Heiko Stuebner <heiko@...> Date: Tue, 15 Apr 2014 01:16:44 +0200

Commit-Message

This adds a node for the clock and reset unit on rk3188 and rk3066 SoCs and also updates the device nodes retrieve their clocks from there, instead of the previous gate clock nodes. Signed-off-by: Heiko Stuebner <heiko@...>
